PAINT.

- Specification of Letters Patent.

- I Patented Aug. 6, 1907.

Application filed February 7,1907. Serial. No. 356,128.

Be it known that I, GEORGE W. ALLEN, a citizen of the United States,residing at Riverside, in the county new and useful Improvements inPaint, of which the following is-a specification.

My invention relates to paints. Its' object is to provide a water-proofand fire proof paint suitable for coating wood or metal and whichpossess such elasticity that when applied to sheet metal the latter maybe bent or handled regardlessly, without danger of the paint cracking orchipping.-

The invention comprehends' essentially the use of California crude oilof asphaltum base as'a body or vehicle to which is added graphite togive it the qualities to resist the elements,'a drier; a suitablethinner, and appropriate coloring matter.

Crude oil, graphite and a drier enter into all my forto conditions. Bycrude oil, I mean crud'eoil of asphaltic base, and of from 8 to 20gravity Baum. Tl e qualities given tothe paint by the use of the crudeoil, are elasticity and resistance to the elements, especiallymoisture.The purposeof the graphite is to give added elasticity and also torender the paint still more resistant to the elements, especially heat.The more the less liable to crack. The amount of graphite to be used toa gallon of crude oil varies from a quarter of an ounce to six ounces,according to the amount of elasticity desired, and according to theconditions under which the paint is to be applied. The graphite has aquality of not only rcndcringsubstances waterproof to which the paint isapplied, but it resists the heat of the sun or the heat arising fromboilers, and so keeps the paint from' running. The more graphite that-isused the better it resists thehcat and'moisture.

. vAs asamplc formula for roofs, bridges, stand-pipes, smoke-stacks,ctcetera, under climatic conditions, such as prevail in SouthernCalifornia, I would use about the following: crude. oil (8 to 20 gravityBaum), 1 gallon; graphiteto lounce; drier, 1 quart; (or litharge of apound.)

If the paint is to be made black, I would add, say i of a pound oflampblack. Of course it is understood portions of the severalingredients may vary slightly from the above, according to theconditions under Wui' i the paint is used. Thus I might use from 1%pints to 2 quarts of drier to a. gallon of crude oil, depending entirelyupon the climatic conditions and as to whether the job needed to bedried in a hurry. For other colors I might employ prince metallic,venetian l red, ocher, or chrome green. Of the first three colors usedthere should be from one to three pounds to a gallon of crude oil,according to the depth of color desired; of the chrome green from one toten ounces would be sufiicient. If the mixture needs thinning I employkerosene, benzin, or crude carbolic acid; the quantity used depending onthe density of the oil and the purpose for which the paint is to beused. On wood the paint is much thinner than on iron and steel. Crudecarbolic acid besides being a good thinner, is a splendid preservativewhen applied to wood, and as a rule would not be used when painting onmetal. It makes no difference what kind of a thinner is used, whetherkerosene, benzin, or other chemical or substance, so long as it servesthe purpose.

Lampblack is used solely for coloring, and the quantity employed'wouldvary from one to 8 ounces per gallon of crude oil, according to theluster and brilliancy desired.

One of the essential elements of the paint is the drier for without thedrier the paint would never dry. Any well known and appropriate liquiddrier may beused. without departing from the spirit of my invention.Whcn'using lit-barge I prefer to employ the same in powdered form.

This paint does not break or crack under force or pressure; even bypounding with a hammer when applied to tin or sheet metal; for instancethe tin may be bentpr broken without even making a crack in the paint;it also preserves the material-on which it is spread, muchbettcr thanordinary point.

In the preparation of the paint, the oil should be heated suflicicntlyto evaporate all the water from it, since the drier the oil is thebetter it is for the paint. It makes very little difference at whattemperature the mixture is made aside from producing in the first placeand before mixing the necessary dryness just montioncd. l

Having thus described my invention, what I claim and desire to secure byLetters Patent, is,

if paint comprising the following ingredients in cornhlnulion: crude oilof from 8" to 20 gravity Bnuni, a drier. :1 suitable thinner, andcoloring mutter.

2. A point having in combination the following ingro- (Hoots in aboutthe following proportions: crude oil of aspl-mltic vlmsv. one gallon;graphite, approximately one ounce: drier, approximately one quart; and:1 suitable coloring mutter.

in testimony whereof I have hereunto set. my hand in prosi-nco of twosubscribing witnesses.

GEORGE w. ALLEN.
